In this research, a microstrip patch antenna was designed suitable for GSM applications (Global System for Mobile) at the frequency of 1.8 GHz, between the two frequencies (1.71-1.805GHz), using an epoxy FR-4  substrate with an isolation constant of 4.3 and a thickness of 1.6 mm, and improving its radiative properties using a combination of One of the procedures is to obtain an antenna suitable for use in wireless communication applications, Where the ground level was reduced only against the transmission line, and rectangular cracks were made in the ground level, and cuts were added to the two letters E and facing each other in the metal patch to increase the beam width, and the antenna was fed using the microstrip line technology. The thickness of the substrate changed as a thickness of 3.2mm was taken, then the third thickness of mm 2 was taken. The results of changing the frequency beamwidth for each thickness were compared, so the frequency beam width at the thickness 3.2 was equal to 0.49051GHZ with a working frequency of 1.8001GHZ, but when the thickness was 1.6mm, the frequency beam was equal to 0.33287GHZ with a working frequency of 1.8891GHZ and a beamwidth at a third thickness of 2mm is 0.41308GHZ and a working frequency of 1.8573GHZ. The microstrip patch antenna was designed and the results simulated using (CST) V. 2019 Software
